l IMPROVEMENT IN HARVESTERS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all who-m it mag/'concern Be it` known that we, GRANT T. GooLMAN andCHARLES M. YOUNG, both ot"Goiry,-in-the county of Erie, and State ofPennsylvania, have invented certain new aintusefulImprovements in.Harvesters, of which the following is a full, clear, and exactdescription.

The invention herein claimed relates to certain improvements on theharvester, for which Letters Patent of the. United States, No. 88,456,were granted to us March 30, 1869. y Y

The first part of our invention. relates to the devices for raising andlowering the cutting apparatus, and

The improvement consists- A First, in' a novel method of combiningamainfran'ie, a hinged coupling-frame, and .a shoeiixed on-thecoupling-trarne, with a finger-beam hinged to the shoe, an elbow leverpivoted inthe shoe, and a lifting-leverpivoted on the tongue, andconnected with the couplingframe and elbow-lever respectively byindependent cords or chains, so arranged that thev first backwardmovement-of the lever lifts the divider'end of the finger-beam only, andthe continuance of this backward movement lifts the heel end ofthefinger-beam also. In our former patent, above referred to, the sameresult was produced in a less perfect manner by a rocking-lever in Atheshoe,and a single lifting-chain or cord.

The object of the next part .of our invention is to render the tongue ordraft-frame adjustable, and

Our improvement consists, second, in a novel method of combining themain frame, suspended from the main axle, the couplingf-ranie,thettongue carrying the drivers seat 'and lifting apparatus, and pivotedto the main fra-me with 'a slotted bracket and set-screw on the front ofthe frame. In our former patent the tongue was rigid, and theinclination of the tongue or frame could not be varied.

Third, the next part of our invention relates to the shipping mechanism,and our improvement consists in a. novel method of combining anoscillating shaft, sliding endwise inits bearings, with shifting-tbrks,loose upon but moving laterally with the shaft, and taking into thecollars of the clutch-couplings, by which the mechanismis thrown into orout of gear.

Fourth, our improvement further consists in a novel method of combininga shipping-lever, an oscillating shaft carrying a shitting-fork, cams tomove the shaft endwise,and a spring to hold the clutch in gear, unlessheld out of gear by the driver.

In the accompanyingdrawings all our improvements are shown as embodiedin a` machine similar to thai shown in our patent of March 30, 1869,above mentioned. It is obvious, however, that some of ,cur-im`provements may be used without the others, and may also be applied tomachines of a construction dilerent from that herein described.

Figure l is a plan or top view of our improved machine, with thecovering of the gearing removed.

lf`igure`2 is a view in elevation ofthe same, as seen from the dividerside, with the finger-beam in section. Figure 3 is a similar view of thesame, as seen from the front.

. Figure 4 is a view of a. portion of the tongue and fran'iedetached,showing their-mode of adjustment.

. In this instance we. have shown two driving-wheels- A A', turningloosely on a common axle, with which they are connected by backingratchets of any welllinown construction.

The axle turns freelyin bearings on the mainframe B. A coupling-frame,C, is pivoted'y to the main frame, and a` finger-beam, I), is pivotedtothe coupling-frame.

The shoe is made hollow and fixed rigidly on the coupling-frame. The linger-beam is secured to a brace, G, pivoted to the coupling-frame andshoe.

A stud, c, is fixed on the pivot of the brace, and an elbow. lever, c',rocks on the same pivot. A toe on the elbow. lever acts on the underside of the `stud to lift the divider end of the finger-beam. y i

A cord or chain, h, passes over a pulley', h', mounted on .the tongue,to a lifting hand-lever, H, also pivoted on the tongue or tongue-plate,and held by a ratchet and pawl of usual form. Either end of thefinger-beamis yfree to rise and fall independently of the other, and bythe apparatusabove described the dividerend ot' the finger-beam can beraised above the heelend by the hand-lever, and held there by the pawl.`

In order to raise both the coupling-frame andinger# beam, a cord orchain, t, is passed over a. pulley, i', and

connected with the hand-lever H.- This cord i is longer than the otherone hl. The result of this -arrangement iStliat when the hand-lever isretracted, the divider end of the finger-beam is rst elevated,

and then, as the movement is continued,ythe couplingu angle of thetongue and frame may thus be regulated. A tool-box, L, which also servesas a foot-rest for the driver, is fastened upon the tongue by aset-screw,

I, passing through a longitudinal slot in the bottom of the box, bywhich means it may be set nearer to or farther from the drivers seat.

Spur-gears M M' of unequal size are mounted loosely onthe main axle,with which they are locked when the forks enter grooves in this shaft,so that the shaft` while turning independently of the forks moves themeudwse withit.

A shipping-lever, O, pivoted on the main frame, is connected by a link,o, with a crank-wheel, o', on the shaft N.

A cam, p, fixed on the shaft acts on a corresponding cam, p', fixed onthe frame, and thus moves the shaft N endw'ise, as it is oscillated bythe lever O.

A spring, q, on the shaft N holds the clutch m in gear with the largerpinion M on'the main axle, undess thrown out of gear by the driver, andthus drives the cutters at their most rapid speed. To decrease themotion, the gear M is thrown into action by moving the shaft N endwise.'lhe spur-wheels M Mgear respectively into corresponding pinions R Rf oua countershaft, 1, carrying a bevel-wheel, S, which drives acorresponding pinion, s, on a shaft, s, carrying,r an internally-gearedspur-wheel, s2, which drives acorrespending pinion on a crank-shaft, T,which drives the cutters hy acrank and pitman, in the usual way. Thecrank-shaft, it will he observed, is arranged between the gears M M,andis straddled by the shifting forks.

One of the advantages of my mode of arrangingr the gearing and clutchmechanisn'i is, that when unclutched all the gears stop, which would notbe the case were the clutches .in the countershaft. I am also enabled toadjust the clutching-forks on their shaft, to comnensate for any wearofthe clutches.

The other portions ofthe machine having been fully described in ourformer patent above mentioned, need not be again described here.

What .we claim as our invention, and desire to secure by Letteis Patent,is-

,1. The combination of the main frame, the hinged coupling-frame,r theshoe fixed to the coupling-frame, and the finger-beam hinged to the shoeand frame, the stud, the elbow-lever and its chain It, with thelifting-lever and the chain i, attached to the conplirgframe, the wholeconstructed for joint operation, substantially as set forth.

2. The combination of the suspended main frame, the couplingfi'ame, thetongue hinged to the frame, the lifting-lever pivoted on the tongue, andthe. slotted bracket and set-screw, all constructed and arranged assetforth for joint operation.

lating endwise-lnoving rockshaft, the loose shiftingforks, and theclutches, the combination being and operating substaniall y as setforth.

4. '.lhe combina-tion, substantially as set forth, of a shipping-lever,an oscillating sliding-shaft, carrying shiltingforks, cams to move theshaft endwise, and a spring to hold the clutch in gear.

In testimony whereof, we have hereunto subscribed our names.
